IIVIPROVED METALLIC @lL-BARREL.

Specilication forming part of Letters Patent' No. 413.625, dated July 19, 1864.

My invention consists of a sheet-iron cusk or barrel having its body and ends brazed to-f get-her, and being otherwise constructed as described hereinafter, so as to afford a perfectly tight receptacle for the reception and transportation of coal-oil and other like penetrating fluids.

In 'order to enable others to make my invention, I willl now proceed to describe the manner ot' constructing the same.

' 0n reference to the accompanying drawings, which form a part of this specification,

'Figure -l is a seetionalviewl ot my improved metallic Cask for coal-oil, and Fig. 2 an end View of the saine.

The body A of the barrel is of the same form and dimensions as ordinary wooden barrels,'such as are used for containing coal-oil. It is, however, made of sheet-iron, of suitable ,thickness and strength to resist the jars to which it may be subjected during transportation.

The ends B B of the barrel consist of disks of sheet-iron, made convex on onel side and concave on the other by being subjected to the action of suitable dies. An annular flange, a, is formed on the edge'of each of the ends B,

and the exterior of this iiangetits snugly in the body ofthe barrel, at the endf of the same, as seen in Fig. l.

Metal casks have been heretofore made for containing coal and other oils, but the ends have been secured to the bodyby rivetinga tedious operation, and one which does not always insure a joint of suiiicient tightness to prevent the leakage oi' the oil, the penetrating and searching qualities of which are well known. The rivets, too, are apt to become loose, on account ol' the necessity of rolling the barrels from place to place, and subjecting them to severe strains and shocks.

Vhen the endsBB have been driven tightly into the body A, I subject the joints to the process oi' brazing, which renders them as tight as though the body and ends'of the barrel were composed of one continuous sheet' ot` plate-iron. In joining the two ends of -the plate which forni the body of the barrel togethe'r they are held by a few rivets while the process of brazing the joint is practiced. At one point in the body of the barrel, andto the inside of the same, I rivet or braze a mass, I, of iron,'which renders the bodythick enough to receive the screw-plug D, the outer sur:v face of the latter being flush with that of the barrel, so that it can Apresent no impediment to the free rolling ot" the same from place to pla-ce. A square orifice is made in the plug for the reception of the square end of the screw-key E, by means of which the plug can be removed and replaced at pleasure. Another piece, d, of iron, is secured to the inside of one ofthe ends B of the barrel, so as to receive the screw-plug e, which can be readily withdrawn by-a suitable screw-key, to make Way for the spigot through which the oil is withdrawn from the barrel.

Grdinary wooden casks or barrels for containing coal-oil soon become'saturated with that material, which, in many instances, oozes through the pores of the wood; hence the many conflagrations which have occurred in localities where ordinary casks for containing coal-oils are stored. It will be evident that this danger must be obviated by the use ot' my improved oil-barrel, as the jointsare made so perfectly tight by brazing that no leakage can take place.

As to durability, it will be apparent that my improved oil-barrel must be more lasting and less liable to injurythan ordinary wooden barrels.

I claiml as my invention and desire to secure by `Letters Patent- As a new manufacture, a sheetiron cask or barrel having body and ends brazed together, and being otherwise constructed :is-set lorth. for the purpose specified.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
